STOVEPlPE-THIM BLE.

SPECIFICATION forming part of Letters Patent No. 653,460, dated July 10, 1900.

Application filed. November 17, 1899. Serial No. 737,289. (No model.)

To all whom it may concern,.-

Beit known that I, JOSEPH F. SACKSTEDEE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Stovepipe Thimbles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in stovepipe-thimbles; and it consists in an irnprovement of the stovepipe-thimble patented by C. W. Schwanengel and myself March 22, 1893, No. 600,894. The improvements are of such a nature as to simplify and render far more practical the invention described in said Letters Patent, as will be more fully described in the following specification and pointed out in the claim.

In the accompanying drawings, Figurel is a front elevation of the thimble intact. Fig. 2 is an elevation with the face-plate and securing-rim removed. Fig. 3 is a view of the inner side of the face-plate. Fig. 4 :is a sectional view on the line a: of Fig. l. Fig. 5 is a section through the base and face plate.

1 designates the base-plate, having an extended tnbular portion 2, which its in the Wall-opening, and a rim 3 and ears 4, with screw-holes. 5 designates a series of V-shaped lugs on the inner face of said plate and extending from the rim 3 to the inner edge of said plate. The inner sides of these lugs lie flush with the edge of the rim. 6 designates a series of slides which are inolosed between said lugs. These slides have their inner ends curved to fit the form of the pipe and aremovable in and ont to inclose dierent sizes of pipes. The dotted lines in Fig. 2 indicate the movement of said plates or slides. Upon each of said slides there is ixed a block '7, which has a groove 8. The said groove has its sides rounded, so as to make the ends thereof Wider than intervening portions. This is an essential feature in the construction of these blocks.

9 designates a face-plate the opening of which is of the same diameter as the Opening in the base-plate. The outer edge of said face-plate has a rabbet 10 and the inner edge a flange 11. Vhen said plate 9 is in position on the base-plate, the lower surface of the rabbeted edge lies below the edge of the rim 3 ofthe base-plate, and thus forms a groove 12.

13 designates aseries of curved ribs or cams on the inner side of the face-plate. Two of these ribs terminate in shoulders 14, which join the inner and outer rims of said plate and form stops to limit the movements of said plate, which movements are given said plate by means of a finger-knob a. One of the ribs 13 fits in each of the grooves 8, and as said plate is moved in a circle according to the direction which is given it the slides 6 are likewise moved in and out, as indicated in the dotted lines. In this movement of said plate the enlarged ends of the grooves 8 enable the ribs 13 to travel in said grooves free from any binding, and the slides 6 are moved Without any impediment. The lugs 5 serve as guides to keep said slides in position against undue lateral movement.

15 designates a securing-ring the inner side of which has a rabbet 16, that nts over the edge of the rim 3 and into the groove 12, formed by the union of the base and face plates. The outer side of said ring lies flush with the outer side of the face-plate when said ring is in position. The said ring has ears 17, with screw-holes, by means of which it is secured to the ears 4 of the base-plate.

Having described my invention, I claim- The herein-described stovepipe-thimble, consisting of a base-plate adapted to be projected into an opening in the wall and having on its inner face a series of V-shaped lugs, slides inclosed between said lugs and guided in their movements thereby, blocks secured to said slides said blocks having slots therein which slots are essentially wider at their ends than elsewhere, a face-plate,a series of curved ribs or cams ou the inner side of said faceare securely united, substantially as shown plate which lie in the grooves or slots in said and described. 1o blocks and two of which ribs terminate in In testimony whereof I ax my signature shoulders or stops which limit the movement in presence of two Witnesses.
